1 x 908gNutrisport - aspartame free 90+ protein - banana 908g: the whey protein in nutrisport 90+ protein is absorbed quickly, having a very high biological value and an anabolic effect that lasts a couple of hours. the micellar casein in 90+ protein is absorbed much more slowly, giving a sustained anti-catabolic action. it has therefore been recommended to take whey protein isolate in the morning and micellar casein but not any denatured casein last thing at night. so nutrisport 90+ provides the best of both for muscle growth at any time of the day or night. calorie free sweetener (aspartame free), low in fat and carbohydrate, supports muscle growth/reduces muscle breakdown, high bv whey protein isolate, slow digest micellar casein, quick but prolonged release of amino acids to muscles, highest protein percentage of any protein in it's class.
